Abstract

The invention discloses a method and system for manufacturing urea solution for vehicles. The manufacturing method includes: S1 high-purity water production, S2 configuration of urea solution for vehicles, S3 filtration and purification of urea solution for vehicles, and the production process is controlled by The unit and each data acquisition sensor can control the quality and monitor data in real time, and transmit the data to the mobile terminal through the cloud platform. The manufacturing system includes a control unit, a cloud platform and a mobile terminal, as well as a water supply unit and a feed unit, as well as a urea solution manufacturing unit and a filtration purification unit; the control unit is used for the control, data collection, data analysis and automatic control of the entire system . In summary, a method and system for manufacturing urea solution for vehicles of the present invention can automatically produce urea solution for vehicles with qualified urea solubility, reduce the intensity and frequency of manual operations, and automatically complete the production of urea solution for vehicles. Manufacturing, and mobile terminals can be monitored and viewed in real time through the cloud platform.

Description

technical field [0001] The invention belongs to the technical field of urea solution for vehicles, and in particular relates to a method and system for manufacturing urea solution for vehicles. Background technique [0002] Urea water has the function of purifying NOx, and is widely used in the gas purification system of large diesel vehicles. Automotive urea, it is a liquid used in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. The scientific name of urea for vehicles is diesel engine exhaust treatment fluid. In China, it is commonly known as urea for vehicles, urea for vehicles, environmental protection urea for vehicles, and denitration agent for vehicles. The most commonly used urea for vehicles is vehicle urea. Urea for vehicles is used to reduce nitrogen oxides. It can be used as a reducing agent in the SCR (Selective Catalytic Reduction) system. It uses aqueous urea for vehicles to react with nitrogen oxides in the exhaust of diesel vehi...

Problems solved by technology

[0003] Traditional vehicle urea is prepared by mixing urea raw materials and deionized water in a certain proportion to make a urea solution, and then filling it after filtering and passing the inspection. The traditional inspection is sampling inspection, which is cumbersome and efficient. Low, and if there are unqualified indicators in the production process, it cannot be discovered in time; in addition, the current production equipment relies on manual feeding, which will cause unstable product quality, and the links between the various steps are not tight, the labor intensity of the workers is high, and the production efficiency is relatively high.
